In this text, the symbol __________ is used for distance travelled to be consistent with A level maths and physics.

$$s$$

The formula used to calculate average speed is average speed, $v =$ __________.

$$\frac{\text{distance moved, } s}{\text{time taken, } t}$$

A speedometer in a car shows its __________ speed, which changes from instant to instant.

instantaneous

In physics exam questions using metric units, the symbol 'm' is the abbreviation for __________.

metres

When rearranging the speed equation to make distance moved the subject, distance moved, $s =$ __________.

$$\text{average speed, } v \times \text{time, } t$$

When rearranging the speed equation to make time taken the subject, time taken, $t =$ __________.

$$\frac{\text{distance moved, } s}{\text{average speed, } v}$$

In the speed trap experiment, step 1 requires measuring __________ from a start point along the side of the road.

$$50\,m$$

In the speed trap experiment, if a car takes $3.9\,s$ to travel $50\,m$, its average speed is __________ (to one decimal place).

$$12.8\,m/s$$
